Beef Research Report, 2003

The purpose of this research was to determine the parentage of animals generated by multiple sire technique. Test of paternity was performed on 63 Angus animals, belonging to 29 families within the Rhodes breeding project, using multiplexed microsatellites. Paternity was determined for 23 families. One of the two possible sires was excluded with multiple markers for 19 families and with a single marker for four families. One of the possible sires was excluded for two families but DNA was not available for the other possible sire. Thus it wasn’t possible to confirm paternity. Four families had both possible sires ...
